Loading up new databases on a GPSIII
I've got a GPS III with the atlantic database that it was shipped with. Planning to do a bit of US flying in the spring and want to have the americas database as well.
Does anyone know what I need to do to get the US database into the unit as well (i.e, have both the atlantic and americas database on the machine). I've had a look at the garmin & jepessen sites but its not clear whether the downloads are new databases or just updates.
Cheers & happy new year to all.
